    CPC classification number: C01C3/0204

    Abstract: DONDE: a) UNA MEZCLA DE AGUA, FORMAMIDA, COMPONENTES DE ALTO PUNTO DE EBULLICION Y GASES DISUELTOS SON EXTRAIDOS POR CONDENSACION DEL PRIMER DESTILADO DE LA MEZCLA DE GAS DE PRODUCTO DESPUES DE LA DESHIDRATACION CATALITICA DE FORMAMIDA GASEOSA EN PRESENCIA DE OXIGENO, PARTE DEL AGUA Y LOS GASES DISUELTOS SON SEPARADOS DEL PRIMER DESTILADO PARA DAR UN TERCER DESTILADO QUE COMPRENDE AGUA, FORMAMIDA Y COMPONENTES DE ALTO PUNTO DE EBULLICION, Y UNA CORRIENTE DE RECICLADO CONTENIENDO FORMAMIDA ES SEPARADA DEL TERCER DESTILADO POR DESTILACION SIMPLE; Y, b) HACER RECIRCULAR LA CORRIENDE DE RECICLADO HACIA LA REACCION DE DESHIDRATACION, EN DONDE DICHA CORRIENTE CONTIENE DE 5% HASTA 50% EN PESO DE AGUA. LA DESTILACION SIMPLE SE REALIZA A UNA PRESION DE 0,0204 A 0,153 Kg/cm2 Y A UNA TEMPERATURA DE 110 A 160°C; Y LA DESHIDRATACION CATALITICA A UNA TEMPERATURA DE 400 A 600°C Y A UNA PRESION DE 0,0714 A 0,357 Kg/cm2

    Abstract: Use of aqueous dispersions comprising at least one at least partially neutralized ethylene copolymer wax selected from among ethylene copolymer waxes which comprise, as comonomers in copolymerized form, (A) from 26.1 to 39% by weight of at least one ethylenically unsaturated carboxylic acid and (B) from 61 to 73.9% by weight of ethylene, and ethylene copolymer waxes which comprise, in copolymerized form, (A') from 20.5 to 38.9% by weight of at least one ethylenically unsaturated carboxylic acid, (B') from 60 to 79.4% by weight of ethylene and (C') from 0.1 to 15% by weight of at least one ethylenically unsaturated carboxylic ester, as auxiliaries for wastewater treatment.

    Abstract: An ethylene terpolymer wax comprises units derived from ethylene (40-95 wt.%), units derived from at least one anhydride of 4-10C-dicarboxylic acid having ethylenic carbon-carbon double bond (0.1-40 wt.%), and units derived from ester having a molecular weight of up to 20000 g/moles (0.1-40 wt.%). An ethylene terpolymer wax comprises 40-95 wt.% units derived from ethylene, 0.1-40 wt.% units derived from at least one anhydride of 4-10C-dicarboxylic acid having ethylenic carbon-carbon double bond, and 0.1-40 wt.% units derived from ester of formula I having a molecular weight of up to 20000 g/moles. R1 = H, 1-10C alkyl, 3-12C cycloalkyl, or 6-14C aryl (preferably H or Me); R2 = 1-10C alkyl, 3-12C cycloalkyl, or 6-14C aryl (preferably Me) An Independent claim is also included for preparation of ethylene terpolymer wax by polymerizing ethylene, ester (I), and anhydride of 4-10C dicarboxylic acid at 500-4000 bars and 170-300degreesC.
